Frost lizards where small 3‑foot-long (0.91‑meter) white creatures that could glide on snow and ice. Their scales' coloring made them almost invisible in snow as long as they remained still.
Frost lizards laid hidden in the snow using their natural camouflage until they spotted their prey. They glided into attack using their breath weapon— spitting out ice balls at a 10‑foot (3‑meter) range. When they approached close enough to the prey, they swiped at it with their sharp claws.
Frost lizards were aggressive hunters. They especially had a taste for the horses and oxen of the caravaneers moving through the lizards' hunting grounds.
